One out of 10 Americans owns a smartphone but has no other Internet service at home, with the poor far more likely to find themselves in this situation than those who are well off, according to a Pew Research Center report released today.
"10 percent of Americans own a smartphone but do not have broadband at home, and 15 percent own a smartphone but say that they have a limited number of options for going online other than their cell phone," Pew Senior Researcher Aaron Smith wrote. "Those with relatively low income and educational attainment levels, younger adults, and non-whites are especially likely to be 'smartphone-dependent.'”
Pew said that 7 percent of Americans are in both categories—a smartphone is their only option for using the Internet at home, and they have few easily available options for going online when away from home. Pew refers to these Americans as "smartphone-dependent."
